YOFC G.654 FarBand® Ultra Low Loss and Large Effective Area Fibre

For the next generation optical transmission network, lower attenuation or larger effective area of the fibre can help the system meet 3U (Ultra high speed, Ultra large capacity, Ultra long-haul) features. Now YOFC can deliver you larger effective area and lower attenuation within one fibre: FarBand® Ultra.

Characteristics

Larger effective area reduces nonlinear effect and enables higher signal power launched into the transmission system
Enable higher transmission speeds with more wavelengths over ultra long-haul distances
Lower attenuation level which meets the demand of extended long distance transmission
Reduce number of repeaters and minimize CAPEX and OPEX
Lower bending induced loss to meet complicated deployment conditions and cable structures
